I was booked on a 9:00pm Continental Express CLE-DTW, and when I got to the gate early, the agent asked me if I would mind taking a 9:05pm Northwest nonstop-- and she gave me $300, which I really didn't expect. I went to the NW gate and Gold upgraded. $300 for 5 minute delay and a gate change isn't bad at all.

Fact: your Northwest flight to DTW will _always_ arrive at the end of the C, and the moving walkway will _always_ be broken.
